How Lehi Handles Noise Ordinances: A Practical Guide
Lehi maintains 115 local ordinances across all categories, and 6 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Lehi falls on the strict-to-permissive spectrum compared to other cities.
Decibel Limits
Lehi sets hard dBA ceilings by zoning classification and time of day. Residential and agricultural properties cap continuous and intermittent noise at 85 dBA by day and 55 dBA at night, with commercial and light industrial zones held to 85 dBA day and 65 dBA night.
Key details: Residential day limit: 85 dBA. Residential night limit: 55 dBA. Commercial/industrial night limit: 65 dBA. Minimum duration to violate: 30 continuous seconds. Penalty: Class C misdemeanor, per § 1-4-1.
Exceeding the applicable dBA table is a class C misdemeanor under Lehi City Code § 5-3-8, punishable per § 1-4-1, with each day of continuing violation charged as a separate offense. Responsibility can fall on the person creating the noise, the business or contractor operating the equipment, or the property owner or tenant who permits it, per § 5-3-7A.
Quiet Hours
Lehi's noise code splits every day into a daytime window, 7:00 a.m. to 10:00 p.m., and a night window, 10:00 p.m. to 7:00 a.m. Every decibel table in the noise chapter drops sharply for the night window, effectively creating the city's noise curfew.
Key details: Day window: 7:00 a.m. to 10:00 p.m.. Night window: 10:00 p.m. to 7:00 a.m.. Residential night dBA (continuous): 55 dBA. Residential day dBA (continuous): 65 dBA. Penalty: Class C misdemeanor.
Sound that exceeds the applicable night-window dBA limit is a class C misdemeanor under § 5-3-8, subject to the penalty schedule in § 1-4-1, with every additional day of violation charged separately. The responsible party can be the person making the noise, a business operating the equipment, or a property owner who allows it to continue, per § 5-3-7A.
Construction Hours
City and state roadway construction projects in Lehi are exempt from the general noise chapter only during typical working hours of 6:00 a.m. to 10:00 p.m. Working outside that window requires a written City Administrator permit stating a maximum dBA limit.
Key details: Exempt working hours: 6:00 a.m. to 10:00 p.m.. After-hours option: Written City Administrator permit. Permit scope: One project only. Covered work: City or state roadway construction. Penalty for violating permit terms: Class C misdemeanor.
Violating the terms of a nighttime roadway construction permit, including exceeding its stated dBA limit, is a class C misdemeanor under § 5-3-7(A)(1) itself, punishable per § 1-4-1 of the code. Liability under § 5-3-7A can reach the contractor operating the equipment as well as the entity that obtained the permit.
If you are coming from a city with tighter rules, you will find Lehi gives residents more flexibility on construction hours.
Vehicle Noise
Lehi makes it unlawful to operate a vehicle with its engine compression brake, or 'jake brake,' engaged anywhere in the city except to avoid imminent danger, under City Code section 7-1-4. The sound of the compression noise itself counts as proof of the violation, and it's a class C misdemeanor.
Key details: Ban: engine compression brakes citywide. Exception: only to avert imminent danger. Proof: compression noise is prima facie evidence. Penalty: class C misdemeanor. Max fine/jail: $750 / 90 days.
Using a jake brake anywhere in Lehi outside an emergency stop is a class C misdemeanor under section 7-1-4.C, punishable by up to $750 and up to 90 days in jail under section 1-4-1, with each day of continued violation charged separately.
Compared to other cities, Lehi takes a harder line on vehicle noise. The enforcement and penalty structure reflects that.
Barking Dogs
Lehi City Code treats a dog that barks, whines or howls excessively, continuously or at untimely hours as a nuisance animal, and keeping a nuisance animal in the city is unlawful. The police department investigates barking complaints and can order the noise abated within two days before impounding the animal.
Key details: Nuisance trigger: Excessive, continuous or untimely barking/whining/howling. Complaint required: City investigates on neighbor complaint. Abatement window: 2 days to fix after notice. Enforcement: Police department investigates and impounds. Penalty: Class B misdemeanor, up to $1,000.
Keeping a nuisance animal is a class B misdemeanor under section 6-4F-1, punishable by up to $1,000 in fines and up to six months in jail under section 1-4-1, on top of any impoundment ordered during the abatement process. Each day the barking continues after the two-day abatement notice can support a new citation, and repeated nuisance findings count toward the three-strikes rule in section 6-4A-9 that can strip an owner of the right to keep any animal in Lehi for a year.
Amplified Music & Outdoor Sound
Amplified music is a named "Public Disturbance Noise" in Lehi, capped at 65 dBA daytime and 55 dBA nighttime in residential zones, with a hard 105 dBA ceiling in bars, restaurants and other entertainment venues that triggers a mandatory 10-minute quiet break.
Key details: Category: Public Disturbance Noise (§5-3-1.B.1.c). Residential continuous limit: 65 dBA day / 55 dBA night (§5-3-6.B). Entertainment venue cap: 105 dBA hard ceiling (§5-3-6.E). Cap remedy: Mandatory 10-min break below 85 dBA. Penalty: Class C misdemeanor, up to $750/day.
Amplified music exceeding the zone-specific dBA limits in section 5-3-6(B)-(C), or a venue sustaining 105 dBA or more without taking the required 10-minute quiet break under section 5-3-6(E), is a class C misdemeanor under section 5-3-8. Each day the violation continues is a separate offense, punishable by up to $750 and up to 90 days under section 1-4-1.
The Bottom Line
Lehi's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Lehi is broadly strict or permissive.
